Draba crassifolia, D. albertina, D. nemorosa, and D. stenoloba in Canada and Alaska

The cytotaxonomy of four species of Draba that are invariably confused with one another is discussed and a key is given. The species are D. crassifolia Graham (n = 20); D. albertina Greene (n = 12); D. nemorosa L. (n = 8); and D. stenoloba Ledebour (n = 20). Characteristics of sterile artificial fir...

Description
Summary:The cytotaxonomy of four species of Draba that are invariably confused with one another is discussed and a key is given. The species are D. crassifolia Graham (n = 20); D. albertina Greene (n = 12); D. nemorosa L. (n = 8); and D. stenoloba Ledebour (n = 20). Characteristics of sterile artificial first-generation hybrids between D. crassifolia, D. albertina, and D. stenoloba are presented and analyzed.
